32 bits not 32 bytes.
thank u Michal,
for correction

Answer 1

int is 32 bits, not 32 bytes
it does not depend on the value in the variable
it will be always 32 bits = 4 bytes

Answer 2

(meta) Why? Because it's faster to retrieve aligned data (you know it's always a certain distance away) than arbitrarily-sized data (must do a full scan).

Answer 3

Yes that is correct. In most languages a type of variable occupies a certain constant amount of bytes.
